Cruel work break HD

Description: I feel like taking a nap, i'm at work, training a client and i can't stop yawning. so i take a coffee break. i drink it and start yawning again, fuck, why isn't this coffee working!? on top of that i feel my stomach jump from the hiccups and burp in my throat. my boss sees me, she's pissed because my break is too long. but what can i do? if i'm still yawning, burping and farting! let this stop!
